Hello all,

 

I tried looking at some examples but couldn’t quite figure out. if I were to write a simple query like this

    SELECT ?food ?cooking
    WHERE
    {
      [] wdt:xx ? food.
      OPTIONAL{?food wdt:xx wd:xxx.}
      SERVICE wikibase:label { bd:serviceParam wikibase:language
        "[AUTO_LANGUAGE]". }
    }

 

What are the correct ids that I should be using?
